Title: Refined water manufacturing system for dialysis
Inventor: SAITO KAZUHIRO
IPC: A61K47/02
Filed: 2002-04-12
Abstract: <P>PROBLEM TO BE SOLVED: To generate a clean refined water without endotoxin.  <P>SOLUTION: An endotoxin removing means for removing the endotoxin in a supplied raw water is provided at an upstream from a reverse osmotic film unit, which refines the raw water in which the endotoxin is reduced by the endotoxin removing means to generate the refined water. Thus, a clean water not containing the endotoxin is produced from the water itself introduced into the film unit, and a dialysate liquid is manufactured by using the clean refined water not containing the endotoxin. The endotoxin removing means is provided at the stage of the upstream of the film unit. As compared with a constitution including endotoxin removing equipment at the stage of the dialysate liquid supplying unit of a prior art, a system constitution change of the dialysate liquid supplying unit is not required at all, and hence the dialysate liquid not contaminated with endotoxin can be simply and inexpensively generated.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-05-15
Abstract: <P>PROBLEM TO BE SOLVED: To carry out thinning processing utilizing all pixels.  <P>SOLUTION: When a horizontal component low pass filter subjects pixels to (1,0,1,0,1)/3 filtering with a green pixel in the first line as a noticed pixel, a simple average of the green pixel as the noticed pixel and adjacent green pixels is calculated because a sum total of pixel values of green pixels multiplied by one and red pixels multiplied by 0 is divided by 3. When a red pixel in the first line is taken as a noticed pixel, a simple average of the red pixel as the noticed pixel and adjacent red pixels is calculated in the same manner. Similarly, green pixels and blue pixels in the second line are filtered. Since every fourth pixel of a horizontal component is thinned in a horizontal 1/3 thinning processing part, a thinned pixel group is generated which is constituted of pixels obtained by taking every fourth pixel as a noticed pixel to calculate a simple average value of the noticed pixel and adjacent pixels of the same color. This method is applicable for a digital camera.  <P>COPYRIGHT: (C)2004,JPO
